Sorry for all the messages. I've been doing a bit more research and I'd like some of the folks having problems to try this.
It appears Q35 machines with qemu 4.0+ changed the default ioapic mode to split, which does not work with with certain hardware combinations. This is not a new issue with split mode but it is an issue with qemu 4.0+ changing the default ioapic mode. One suggestion I discovered was to add the following element: <ioapic driver='kvm'/> Inside the <features> element in your machine's XML. You can edit this directly in virt-manager or you can find the machine's XML and edit it manually (look in /etc/libvirt/qemu) for the appropriate XML. It would be great for those people affected to try this simple change out and report back if it solves the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1849720 Title: Running VM with Virtual NIC Crashes Host OS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1849720/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
